Abstract: Aiming at simulation performance verification problem of the flight simulator, the previously collected test flight data and simulation data was studied, the method of simulation model validation data preprocessing was carried on the induction and limitation was pointed out, A set of processing methods to dynamic data and static data of simulator was presented to passage data, remove outliers, sampling points matching, stationarity test and smooth processing, zero mean processing, ergodic property inspection and normality, and these methods were used to the flight test data and simulation data obtained for processing, the data after preprocessing was used for the verification of specific flight performance. The results indicate that the pretreatment method can be gained by the data processing to meet the specific data validation, and the foundation of validation work is laid for the next step.
Key words: data reliability; performance verification; data preprocessing
